LOCK Foe DUMPlNG-CARS.

Specification of Letters Patent.

' Patented May 7, 1907.

Application filed January 2,1907. Serial No. 350,324.

To all whom it may concern: I

Be it known that 1, WILLIAM W. MoKEL= VEY, of Youngstown, Mahoningcounty, Ohio, have invented a new and useful Improvement in Locks forDumping-Cars, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings,-formingpart of this specification, in which-,

Figure 1 is a partial side elevation of a dumping ladle car equippedwith-my invention. and Fig. 2 is an end elevation of the same with thedumping mechanism partlyin section. Figs. 3 and 4 are detail sectionalviews, on a larger scale, showing the lock.

. My invention relates "to dumping cars, more especially dumping ladle.cars which are tippedin either direction, and it particularly relatesto-locking devices employed in securing the ladies of such cars in theirupright position while the cars are being moved from. place to place onthe railway tracks.

In the drawings, 2 represents the ladle supported upon its trunnions 3on the ends of which the gear wheels 4 are keyed, the gears meshing withracks 5 on the end frame of the car. The ladle tip ing motor 6, which isapplied to one end on y of the car, has a piston rod 7 which is securedon its outer end to a cross-head 8. The cross-head 8 is provided withtubular guides or bearings 9 which slide over the two guide rods 10. Theguide rods 10 are secured on their outer ends to the stationary bracketor lug 11 on the end frame of the 'car, their opposite ends being heldin the stationary lugs or brackets 12.

One end of a link 13, having a hole 13 on its other end and a'hole 14intermediate of its ends is pivoted-on the bolt 8 secured to the upperend of the crosshead 8 and the link 13 is detachably secured to eitherof the projecting lugs 15, 15 which are on the upper end of the gearwheel 4 by means of the removable bolt or pin 16 by placing this bolt inone of the openings 13,14 and the registering opening in one of the lugs1'5. The pin 16 is provided with a conical end having an annular groove16'. The bolt is retained in place in the lug 15 or 15 in which it isplaced, by means of the swinging latches 17 pivotally secured on each ofthese lugs, the latch 17 being held by its own .weight in the groove 16to lock this pin inplace, the latch being I lifted by hand to releasethe pin and-permit of its removal.

To lock the ladle 2 in its upright position on the frame 18 of the car,a locking bar 19 is movably secured by means of hinges 20 on the hingebolt 20, the ends of this bolt being secured to-the lugs 11 and 12. Theends of this locking barv engage with the face of one of the slides 9 onthe cross-head 8 andthe face of one of the lugs 12 and kee these partsin their separatedposition, as s own in the drawings.

When the cross-head is attached to the ladle at the other end of itsstroke, by means of the pin 16 which in such case is inserted in theopening 14 in the link 13 and the registering opening in the lug 15*,the ends of the locking bar 19 engage with the opposite end of the slideor bearing 9 and with the bracket 11 to hold the parts from movement andkeep the ladle in the desired position. I

With the parts connected as shown in Fig. 1, the locking bar 19 islifted on its hinges 20 the osition shown dotted. Fluid is then admittedto the right hand end of the cylinder 6, causing the piston 7 a andpiston rod 7 to exert a pushing action through the link '13 upon thepivotal connection to the gear wheel 4, causing the ladle to lift in acounterclockwise direction until the ladle. body strikes the side of theframe member 18 which acts as a stop. The ladle is tilted back to itsnormal osition by admitting fluid to the other end of the cylinder inthe usual manner.

1 If it is desired to tilt the ladle in a clockwise direction, thelocking bar 19 is moved into the position shown dotted. The connectinpin 16 is then drawn-out of the link 13 an fluid is admitted to thecylinder to move the link 13 until its intermediate hole 14 registerswith the hole in the lug 15*. The pin 16 is-then pushed into theregistering openings in the link 13 and lug 15*, the piston then beingat or near the left-hand end of the cylinder 6. Fluid is then admittedto the left-hand end of the cylinder causing the cross-head to pull uponthe connecting link. 13 and swing the ladle in a clock-wise directionuntil the ladle bodystrikes the side of the frame 18. Tilting the ladleto normai .by means of one of its handles 21 until it is in p Topposition is then carried out by admitting fluid to the right-hand end ofthe cylinder. The locking bar 19 is then moved longitudinally on the rodor hin e bolt 21 until its end strikes the lug 11. %l16l00killg bar 19is then turned on its hinges into enga ement,

with the lug 11 and the end of the sli e 9 on the cross-head 8 and theladle is again locked in upright position on the car, in this case withthe tilting motor at the opposite end of its stroke and with the link 13 connected, through its intermediate'hole 14 with the lug 15 on thegear Wheel 4.

Instead of the'motive cylinder shown, an electric or other rotary motormay be employed to move the cross-head. When a motive cylinder is used,the cylinder may be movable and the piston stationary and other 1changesin the form and arrangement ofthe tipping mechanism may be madeto which my invention may be applied,

I claim 1. A ladle car having a movable cross head, with a shiftablelink connected to the trunnions and a longitudinally movablehingedlocking bar arranged to contact with the cross-head and lock theladle upright on the "car; substantially as described. I

2. A ladle car having a movable cross-head with a shiftable linkconnected 'to the trunnions, and a hinged locking bar, the opposite endsof said bar engaging with the crosshead, and a stationary element tolock the ladle in its normal position; substantially as described. y

3. A ladle car having a movable oross-head, with a shiftable linkconnected to the trunnions and a longitudinally movable hinged lockingbar arran ed to engage with the cross-head and 100 the ladle upright onthe car when arranged for tilting in either direction; substantially asdescribed.

4. A ladle car having a movable cross-head, with a shiftable linkconnected to the truncontact with either end of the cross-head and car;substantially as described.

6. In a tipping ladle car, a ladle, a l@dl 6 tipping motor having amovable elementcone'" nected with the ladle, and a longitudinallymovable locking bar arranged to contact with the movable element andlockthe ladle upright on the car; substantially as described.

7. In a tipping ladle car, a ladle, a ladle tipping motor having amovable element movable lockin bar arranged to contact with the movab 0element and lock the ladle upright on the car and arranged for tippingin either direction; substantially as described.
